Is Brucella melitensis aerobic or anaerobic?

aerobic
Cell structure and metabolism. Brucella is a Gram-negative coccobacilli pathogenic bacteria that adapts to an intracellular lifestyle, is non-spore-forming and is non-motile. These organisms are mainly aerobic but some may require an atmosphere containing about 5-10% of carbon dioxide.

Is brucellosis aerobic?

Brucellae are Gram-negative coccobacilli; non-spore-forming and non-motile; aerobic, but may need added CO2.

Is Brucella an Anaerobe?

Brucella is Gram-negative, non-spore-forming, non-motile, facultative anaerobe and intracellular in nature which mainly affect the reproductive tract and cause abortion and infertility in natural host (D’Anastasio et al., 2011).

Does Brucella grow anaerobically?

They are nonmotile, nonencapsulated, and nonsporing; they grow aerobically or microaerophilically but do not grow anaerobically. Brucella abortus, Brucella suis, Brucella melitensis, Brucella ovis, Brucella canis, and Brucella neotomae are the species of Brucella and their natural reservoirs.

What is the difference between Brucella abortus and melitensis?

Brucella melitensis is most commonly acquired from goats and has been acquired from sheep and dromedary camels. Brucella abortus is associated with cattle. Although horses can occasionally become infected, transmission to humans from horses, if it occurs, is very rare.

What does Brucella melitensis cause?

Brucella melitensis, a small gram-negative coccobacillus specific for goats, is the cause of brucellosis in goats as well as cause of Malta fever in humans.

What type of organism is Brucella?

Brucella is a genus of Gram-negative bacteria, named after David Bruce (1855–1931). They are small (0.5 to 0.7 by 0.6 to 1.5 µm), nonencapsulated, nonmotile, facultatively intracellular coccobacilli.

Can Brucella be cultured?

[10,11,12,13,14] In general, blood culture for Brucella is performed by conventional Castaneda method where the blood specimen is directly inoculated in the liquid phase of the Castaneda medium. Although the results by this method are satisfactory in acute untreated cases, the incubation time required is very long.

What grows on Brucella Agar?

4-7 BD Brucella Agar with 5% Horse Blood is particularly useful for the cultivation of all more fastidious aerobic, microaerophilic, and anaerobic microorganisms including streptococci, pneumococci, Listeria, Brucella, Neisseria meningitidis, Haemophilus influenzae and Helicobacter pylori.

Can humans get Brucella melitensis?

melitensis is the most common species of Brucella in human illnesses, with some estimates suggesting that it is responsible for 70% of all infections. Most people acquire this organism by direct contact with infected animals or their tissues, or by the ingestion of contaminated dairy products.

Where is Brucella melitensis found?

Brucella melitensis is the organism most frequently involved and is endemic in many Mediterranean countries, Africa, and Central America; it does not occur in the UK. B. abortus has occasionally caused abortion, but B. ovis has not been isolated from goats.

Is Brucella melitensis oxidase-positive?

Growth may be improved by addition of serum or blood. Brucella spp. are catalase-positive and usually oxidase-positive. Brucella is a monospecific genus (Brucella melitensis) with multiple biovars.
